The lever B is pivotally mounted on the plate B and is adapted; to oscillate so as to close the slot B, being held; however out of engagement with the slot by the spring B The-rod B is slidably mounted on the plate B and is provided with the envelop contacting T-head B projecting forward beyond the edge B and is inpivotal engagement with'the slot B in the end of the lever B.

The envelop moistcning reservoir C, which g is slidably mounted on the angles G on the tively the elastic rollers A, A, A3, A

frames A contains the spring-held roll C sill opposition to the Plate B to moisten the plate. 'The pad 0 is. mounted upon the crosspiece A and in opposition to the roller A to scrape off orabsorb from its surface any moisture which may be left there by the Cir passage of the envelop i as itis fedforward by the plate 13 the rollers A, A. The envelop hopper C'" rigidly attached to the frames A and provided with the fixed rearwardly extending half-bottom C. The plate C having at its forward edge the laterally disposed T-head' C is slidably mounted upon the bottom C above the plate Ti being held in position thereon by the lugs C". The spring C attached at one end to the plate C and at the other end to the plate C is adapted to hold the plate C in the forward position beneath the pile of envelops, thus supporting them. The upwardly extending lugs C limit the forward excursion of the Jlate C the downwardly extending lugs C extending into the path of the plate B in such wise that as the plate 1 retards from the rollers A, it it carries the plate C with it permitting the [lap C of the bottom envelop C in the pile to drop down into the path of the feed plate 13. The plate C is slidaloly mounted within the hopper C as the outwardly curved portion C in opposition to the roller A is held against the roller by the spring C, which is adapted to yield to permit the plate C to ride up as the feed plate ll travels toward the rollers A A. The pivotally mounted guide C" contacts the back of the pile of envelope and holds them against the plate or apron C. The. spring C is adjustable by means of the thumb screw C to vary the pressure exerted by this guide against the enrelops. The hopper C is provided on the driving side of the machine with the false spring side C adjustable in position by the thumb screw whereby the position of the envelops with respect to the stamp allixing mecl'ianism subsequently to be described may be controlled. The rocker-shaft A carries the in or lever D projecting downwardly into the path of the feed plate B and adapted to enter the slot B or contact the end of the lever B as the case may be. The lever D on the end of the rocker shaft A is connected by means of the spring D and link 1) with one end of the bell cranl': level--13 to the other end of which is co'nnected the sliding rod D which carries at its other end the lat cam D. The pin D is slidably mounted in the gear B' in opposition at one end to the cam D and may be caused by it to project from the inner side of the gear B into the path of the star wheel D which is mounted upon the shaft E The shaft D carries the star wheel l) in opposition to the pin D The lever D is provided with the curved slot' D in which is slitlably mounted the pin D projecting inwardly from the roclte arm D The rocker shaft D is driven by the rocker arm l) and carries the lever D" connected by means of the link 1') with the stamp feeding carriage D reciprocating upon the stamp guiding tracks D and carrying the downwardly iressed spring held, stamp perforation engaging fingers D The stamps D are fed from the reel D through the stamp guides into the path of the stamp feeding fingers.

The carriage E is slidahiy mounted upon one the frames A, is provided with the downwardly extending, flange E ha ving the T shaped slot E in the path of the slot engaging projections B on the feed plate B. The arm E projects forwardly from'the arriage E and carries the reservoir E having the stamp moistening pad E on the upper surface thereof. The arm E is pivotally-mounted upon the carriage E, pro vided at one end with the inclined trigger surface E adapted to be engaged by the plate B during its return movement away from. the feed rolls and carries at the other end the stamp engaging spring leaf E in oppositionto the pad E The lever l) is carried by the rocker shaft D and operatcsby means of the link D and lever arm I) the counting mecha nisin if). The lever r pivotally mounted upon the frame A is held in a raised position by the spring F is provided with the cam surface F in the path of the pin D 7 and is connected by means of the link F with the sliding rod l having at its upper end the cross arm F2 The carriage F which is slidably mounted in the vertical guides F, has along one side the stamp cutting knife l in opposition to the end of the stamp guide F and contains slidably mounted therein the perforate stamp prcsser foot or plunger F. The foot F proviocd withthe upwardly extending link F in which is slidably mounted the lever F The spring F is interposed between the lever F and the carriage F in such manner that the stamp is first; cut oil by the knife on the carriage and then conveyed down to the envelop. At the end of the carriages excursioirthe presser foot comes down and presses the stamp against the envelop which at that time rests upon the anvil F below the normal path of the envelop.

t The housing G which contains the. stamp feeding; mechanism and the stan'iptrccl D, the counting mechanism and the stamp reel together with the stamp guides is pivotally' mounted upon the machine and contains the three spaced rollers G, G and G between which the stamps are d awn in reverse di reaction to take out the curl imparted to them by their storage in the roll form.

The cam ll which is rigidly attached to the main frame in the path of the pin D is a daptcd to force it into the inoperative position as it is carried around after it has operated the stamping mechanism.

It will be evident that while I have shown or/see in my 'drawings an operative device, still many changes might be made in size, shape and arrangement of parts without departing materially fromthe spirit of my invention and I wish therefor 'that my drawings be regarded asin a sense diagrammatic.

Theuse and operation of my invention are follows: The envelope are placed in the envelop hopper back down, that is with the "flap on the down side in such manner that the-top edge of the envelop faces the feed rollers. The machine is then started, the rollers rotate and the crank on the drive shaftreciprocates the envelop feeding plate.

5 This plate feeds forward over the moistening roller and engages the inside of the flap of the envelop; it then feeds forward past the'downwardly depending apron in the envelop hopper,- raising it to permit the go passage of'a. single envelop. The false or movable bottom in the hopper comes forward with the envelop feed plate, thus holding-the column of envelops stifi', pre- ,venting their sagging'down. This prevents the flap on the next to the last envelop in the nleff roni catchin any obstructions or perorations In the hottom envelop. The envelopi'is fed over the large idler roll upon whiol'r'the apron restsand the pressure of so the apron on the envelop and roll brings the-liap up against the moistened feed strip, thus'ifmoistening the flap. Thefeed strip goes on until the envelop is inserted between the first-feed roll, when it withdraws, allow .35 ing the envelop to be fed through the mach1ne by the feedi'ollsf' Meanwhile howevent-the slidab-le T head projections at the frontedge of the envelop feedplate will have -:engaged the back of the he of the ento ramp and. have been pushed bacr until it is in line with the fro'nt'of the envelop feed plates. This operates the lever to close the slot in the feed late and the closure of this slot.--.brings an o strnction' into the path of the lever on the stamp feeding rocker shaft.

I This rocks the shaft and throws the clutch, thus connecting the' stamp afixing mechanism'with the driviiig"niechanism,- As the envelop passes through the machine, the forno ward excursioi of the envelop feed. plate carries forward with it the stamp nioistener and feedeixuntil the moistening mechanism lies beneath the last stamp-on the stamp strip. Thereturn movement of the envelop I feeding plate operates the lever on the stamp moistening. carriage, which lever presses against the top of the stamp and presses it down against the moistening pad on the moistener, thus moistening the bottom of 69 the stamp. The stamp cutting and affixing mechanism then operates responsive to the driving means and cuts oil the stamp, subsequently pressing it down against the envelo-p e The cutter and presser then flies up and permits the next stamp to be fed forward by the reciprocating fingers which en gage the stamp perforations. The envelop,

then feeds past the last two feeding and,

pressing rolls, whereby the stamp is firmly pressed against the envelop and the flap is again firmly ressed for sealing. The downwardly curve guide bars below the top of the lower rolls are merely provided to prevent any buckling or bending of the envelop in case thin light envelope might be used with heavy objects inthem such as would cause them to bend downward The feed and rocker shaft to throw the stamp feed clutch.

By this means it is possible to lock the stamp feed case and stamps may not be stolen from this case since the only way to get them out is by feeding the envelops through the machine.
